BARREL-HEATER.

SPECIFICATION forming part of Letters Patent N0.374,069,-datecl November 29, 1887. Application filed July 7,1887. Serial No. 243,660. (No model.)

To all whom, it may concern:

Be it known that I, AMos HIME, a citizen of the United States, residingin the city of vRockford, county of Winnebago, and State of Illinois, have invented certain new and'useful Improvements in Barrel-Heaters, of which the following is a specification. 4

This invention relates to heaters employed in cooperage to heat the barrels or other vessels in the process of their manufacture.

Its object is to envelop the vessel in a heated atmosphere substantially uniform. Y

To this end I have designed and constructed the heating apparatus represented in the accompanying drawings, and which, in connection therewith, will be hereinafter more fully described. y

Figure 1` of the drawings is a vertical central section lengthwise ofthe furnace of my improved heater in isometrical view. Fig. Zis a horizontal transverse section of the chamber of the heater containing the vessel to be heated. Fig. 3 shows an internal application of the fines to the drum of my improved heater.

The furnace employed in this instance is, in the main, a well-known form of stove, preferably made from cast-iron or plate material;

and it consists ofa ire-box, 1, rectangular in section, a return hot air or gas chamber, 2, formed in the upper portion of the furnace by the horizontal division-plate 3, connecting the inner face of the external side and end walls of the furnace, a gas-Hue, 4, rising from the rear portion of the horizontal division-plate 3, a drum, 5, with closed upper end incasing the gas-line 4 and connected at its lower end with the upper plate of the furnace, and a gas-Hue, 6, rising from the forward end portion of the furnace, forming a continuons iiue from the fire-box to the final exit through the. gas-flue v 6, as indicated by the arrows, all of which are substantially such as heretofore in use; also, a

base-plate, 7, fitted to the drum 5, placed on the rear en d of the furnace,- and the barrel 8, to be heated, placed over the drum and supported in place on the base-plate, are substantially such as heretofore used for like purposes.

An outer casing, 9, of drum form,with closed upper end, 'preferably of plate material, is provided with a series of vertical flues, 10, with closed lower ends and vopen upper ends, xed to its outer surface at suitable intervals,

and openings 11 are made in the lower end portion of the drum to open in to the lower end of the several external vertical tlues. This outer drum-casing, 9, is designed to be placed over the barrel concentric thereto, and its or chain, by'means of which the'drum can be readily raised and lowered.

In the use of my improved heater, a fire is made` in the-fire-box, from which 4the gases produced by vcombustion and the heated air will pass through the several flues, as indicated by the arrows. .The drum is then raised from the base-plate by means of the rope or chain connecting it with the counterbalance-weight.

In this process of heating and drying barrels the steam generated from the moisture contained in the material will pass from the outer drum through the openings 11 at its lower end into the vertical outer flues, 10, and escape from their 'openupper ends. In this instance I have placed the flues on the outer surface of the drum, which I prefer; but evidently they may be placed on its inner surfaee,las shown in Fig. 3, and when so placed their open ends will be downward and will extend nearly to the lower end of the drum, and openings 16, through the wall of the drum near its upper end, wilLcommunicate with the closed upper end of the fines; or, instead thereof, the iiues may extend and connect' with opening 17, formed iu the head end, 18, of the drum.

I claim as my invention- 1. The hereindescribed drum, closed at the top and open at the bottom, provided with iiues extending from its bottom upwardly, the

seid ilues communicating with the interior of the drum at the bottom and with the open air at their upper ends, substantially its set forth.

2. The herein-described drum, closed at the top and open at the bottom, provided with ues extending from its lower end upwardly along,` its outer face, the said flucs communieating with the interior ofthe drum at the bottom and with the open air at their upper ends,

Io substantially as set forth.

3. The combination, with the interior or heating drum and a. suitable support for the same, of the removable outer drum provided with vertical flues opening into the space between the drums at the bottom and to the open air at the top, and means for elevating and lowering the seid outer drum, substantially as set forth.

AMOS HIME.
